According to The Sun, Lukaku was unhappy that Pogba did not allow him to take a penalty in the latter stages of the clash, with the Belgium forward having the chance to complete his hat-trick having already scored twice.

The report claimed that the pair 'had to be calmed down as they went at it' in the dressing room.

However, Lukaku took to social media on Tuesday morning to seemingly deny that there had been any type of altercation with the France international, who missed the late spot kick against the Saints.

Lukaku will be looking to add to the four goals that he has managed in his last two Premier League appearances when United travel to Paris Saint-Germain for the second leg of their last-16 Champions League tie on Wednesday night, but Pogba is suspended for the Red Devils.
